癖が付かずにいつまでも新品と同様に使用出来る。従来

い時にまっすぐであった繊維材が使用するに従って折れ
曲がって使い難くなる。When a fiber material with excellent elasticity and shape retention is used, for example, as a fiber material for brooms and brushes, it can be used like new forever without becoming bent. Conventional brooms and brushes made of synthetic resin fibers or the like are straight when new, but as they are used, the fibers bend and become difficult to use.

特長が実現できる。Furthermore, synthetic resin fibers have extremely high electrical resistance and are easily charged with high-voltage static electricity, but by embedding metal fibers in them, it is possible to improve conductivity and effectively discharge static electricity.
更に、形状記憶合金等の独特の物性を有する細繊維を埋

い物性を持たせることが出来る。Furthermore, by embedding fine fibers such as shape memory alloys having unique physical properties, it is possible to impart physical properties that cannot be achieved with synthetic resin fibers alone.

しかもこれを安価に多量生産することは極めて難しい。However, for any of these fibers, it is important to embed the fine fibers in alignment with the fibers in the longitudinal direction. By embedding even thinner fibers within the thinner fibers in the same direction,
Moreover, it is extremely difficult to mass-produce this at low cost.
特に、方向を揃える為に生産性が著しく低下する。In particular, the productivity is significantly reduced due to alignment of the directions.

維の表面を溶融合成樹脂でコーティングする状態で、合
成樹脂を押し出して金属線埋設の繊維を製造している。For example, the method disclosed in Japanese Patent Application Laid-Open No. 51-11909 involves extruding a molten metal fiber into the center of the fiber, coating the surface of the metal fiber with a molten synthetic resin, and then extruding the synthetic resin to embed the metal wire. manufactures fibers.

生産できない。However, with this method, only specific metal fibers with a low melting point can be used, fine fibers with a high melting point cannot be embedded, and furthermore, a unique and complicated die is required, making it impossible to mass-produce at low cost with simple equipment.
更に別の製造方法として、あらかじめ別に製造されたふ
たつの繊維を防糸する技術も開発されている（特開昭４
９−３６９１６号公報）。As another manufacturing method, a technology has also been developed in which two fibers that have been manufactured separately are yarn-proofed (Japanese Patent Laid-Open No.
9-36916).

ゆる種類の細繊維を埋設出来ない欠点があった。This method has the advantage of being able to produce fibers in large quantities at low cost;
It takes time and effort to thread-proof the manufactured fibers, which does not improve overall productivity.Furthermore, the two fibers to be thread-proofed are those that can be attached to each other when heated, making it possible to make all kinds of fine fibers. There was a drawback that it could not be buried.
本発明はこれら従来の欠点を除去することを目的に開発
されたもので、この発明の重要な目的は、極めて簡単に
繊維の方向性が揃えられ、ｍ繊維埋設繊維が安価に多量
生産できる繊維の製造方法を提供するにある。The present invention was developed with the aim of eliminating these conventional drawbacks, and an important purpose of the present invention is to make it possible to easily align the fiber direction and to produce m-fiber embedded fibers in large quantities at low cost. To provide a manufacturing method.

を提供するにある。Another important object of the present invention is to provide a method for producing fibers in which most types of fine fibers having a melting point higher than that of the fibers can be embedded.
［従来の問題点を解決する為の手段］

後延伸されて細繊維が繊維の長手方向に揃えられる。[Means for Solving Conventional Problems] A method for producing a fine fiber embedding fiber embeds a short fiber 111i11 whose melting point is higher than the melting point of the fiber. Fine fibers are mixed with fiber raw materials and melt-spun. The melt-proofed fibers are then drawn to align the fine fibers in the longitudinal direction of the fibers.
［作用効果コ
繊維内に混合されて防糸された細繊維は、ダイから押し
出されたときに方向を揃える必要がない。[Operations and Effects] It is not necessary to align the direction of the yarn-proof fine fibers mixed within the fibers when they are extruded from the die.
押し出し後、延伸されることによって細繊維の方向が延

ての製造工程は従来のモノフィラメントの製造と殆ど変
わらず、単繊維では実現出来ない優れた特性の細繊維埋
設繊維が安価に提供でき、種々の用途に最適繊維として
使用される。After extrusion, the fine fibers are stretched in the stretching direction, that is, in the longitudinal direction. Therefore, there is no need to align the direction of the fine fibers vertically in the step of extruding the fibers from the die, as in the conventional method. That is, it can be produced in large quantities at low cost in almost the same way as ordinary monofilament without embedded fine fibers. Furthermore, most fibers are stretched after being extruded from a die in order to increase their strength, so this stretching process can also be used to align the direction of the embedded fine fibers, making the overall manufacturing process similar to the conventional one. It is almost the same as the production of monofilament, and it is possible to provide fine embedded fibers at low cost with excellent properties that cannot be achieved with single fibers, and they are used as optimal fibers for various purposes.
更に、細繊維は繊維の原料に混合して押し出しされて繊

繊維と一緒に押し出して繊維状に成形する必要がなく、
また、細繊維を付着して結合するものでないので、細繊

が使用できる。Furthermore, since the fine fibers are mixed with the fiber raw material and extruded and embedded within the fibers, there is no need to melt the fine fibers and extrude them together with the fibers to form them into a fibrous form, as in the past.
In addition, since fine fibers are not attached and bonded, almost all fine fibers having a melting point higher than the melting point of the fibers can be used as the fine fibers.
［このましい実施例コ 以下、この発明の実施例を図面に基づいて説明する。[Desirable example code] Embodiments of the present invention will be described below based on the drawings.

ｍ、好ましくは、１〜１０ｍｍの範囲に決定される。The fine fibers to be mixed with the synthetic resin raw materials are fine fibers with a higher melting point than the synthetic resin, such as glass fiber, rock wool, and metal crystals, so that they do not melt together with the synthetic resin when the synthetic resin is melt-spun. Fibers, shape memory metal WC fibers, synthetic resin fibers with a high melting point, etc. can be used. The longer these fine fibers are, the better their strength and physical properties are, but if they are too long, it becomes difficult to extrude them smoothly from an extruder. In particular, fine fibers that are too long should not be used as they tend to clog the die nozzle.
It gets wrapped around the extruder screw and cannot be transferred smoothly. Therefore, the length of the fine fibers is usually 0°5 to 30m.

ンの範囲に調整される。The thickness of the fine fibers is determined to be the optimum value depending on the thickness of the monofilament after drawing, but it is usually less than half the thickness of the monofilament, for example, when the thickness of the monofilament is 500 to 3000 deniers, The diameter of the fine fibers is usually adjusted to a range of 5 to 500 microns, preferably 10 to 300 microns.

通常０．３〜７０重量部、好ましくは１〜５０重量部の
範囲に決定される。If the mixing ratio of fine fibers is too low, the characteristics of the mixture of fine fibers will not be exhibited, and on the other hand, if the mixing ratio is too high, the strength will decrease. The amount of fine fibers to be mixed is usually determined to be in the range of 0.3 to 70 parts by weight, preferably 1 to 50 parts by weight, based on 100 parts by weight of the synthetic resin raw material pellet.
